MEANS FOR COUPLING AIRICUl-TURAL MACHINES TO MOTORS.

SPECIFICATION forming part of Letters Patent N 0. 729,275, dated May 26, 1903.

Application filed February 25, 1903. Serial N0. 145,033- tNo model-l I To ctZZ whom it may concern:

. Be it known that I, ANDRE CASTELIN, a citi zen of the French Republic, residing at 17 Rue certain new and useful Improvements in Means for Coupling Agricultural Machines or Apparatus to Motors by which They are Traversed OvertheLand, of which the following is a specification.

This invention relates to means whereby agriculturalmachinesorapparatussuch,for example, as those employed in harvesting, mowing, binding, manuring, or sowing-are coupled to a motor (which I will call the tractor) by which they are traversed over the land, the object of this invention being to provide an improved coupling arrangement.

The arrangement according to this invention consists in the combination of two frames jointed together, one frame being pivoted to the tractor andthe other frame being pivoted to the first frame, so' that good distribution of the load and perfect adjustment of the height of the machine above the ground can be secured. V

In order that this invention may be clearly understood, I shall describe it with reference to the accompanying drawings, of which Figure l is a lateral View of the improved coupling arrangement. Fig. 2 is the plan.

The frame 1 of the tractor is provided on its fore part with strong brackets 2 2, each of which carries two bearings 3, in which can turn a vertical screw-threaded rod 4, working in a nut 5, connected to the side bars 7 of the movable frame, pivoted to the tractor-frame. The said vertical rods can be rotated by a crank-handle or hand-wheel 6 and the screwnut, so that the point of attachment of the said movable framecan be adjusted vertically. The side bars 7 of the said movable frame are preferably of channel-irons and extend in one direction below the frame of the tractor to, say, about the center, of the tractor, where their ends 8 bear on a strong laminated spring 9, and in the other direction the said side bars extend beyond the tractor and diverge from each other and are connected by a transverse rod 10 or bolt around which can turn the second wooden frame ll,(preferably with side barsdiverging like those of the first frame,)supporting the agricultural appliances. The outer ends of this second frame 11 carry laminated springs 12, the forward ends of which carry lenticular or other shaped wheels 13 to bear on the ground. At the otherend of the said second frame is secured a lifting-bar 14, carrying a vertical rod 15, provided with a screw-nut 16, in which works a screw-rod 17, provided at its upper end with a crank-handle 18 or handwheel within reach from the drivers seat 19. By turning this screw-rod 18 the height of the operating part of the machine above the ground can be adjusted, or the said part can be raised completely away from the ground when requiredfor example, when traversing harvesters along ordinary roads.

Besides its simplicity the arrangement according to this invention has the advantage of concentrating the whole weight of the machine on the leading wheel, which is generally the driving-wheel, and of thus increasing the adhesion of the tractor on the ground. Moreover, the load being distributed nearly equally on each side of thewheel-axle lifting of the rear of the tractor does not take place.

I Havingnow described myinvention and in what manner the same may be performed, I declare that what I claim is 1. In agricultural machines or apparatus coupled by their back side to a motor or tractor an improved coupling arrangement having a frame 7 jointed to the motor by a screw-nut which can be adjusted vertically and a laminated spring, a wooden frame 11 supporting the agricultural appliances, a transverse rod 10 connected to the frame 7 and on which the frame ll is pivoted, a lifting-bar. 14 secured to the said frame 11, a screw-rod 17 and a crank-handle 18 within reach from the drivers seat for operating the said bar, substantially as described.

2. The combination with a traction device, of a supporting-frame pivotally and adjustably connected therewith, and a frame pivoted to the supporting-frame and adjustably connected with the traction device.

3. The Combination with a traction device, of a spring carried thereby, a supportingframe pivotally and adjustably connected with the traction device and havingitsinner end adapted to bear against said spring, and a frame pivoted to the supporting-frame and adjustably connected with the traction device.

4. The combination with a traction device, of a spring carried thereby, a supportingframe pivotally and adjustably connected with said traction device and having its inner end bearing against said spring, a frame pivoted to the supporting-frame and adjustably connected with the traction device, a pair of Wheels,and springs for connecting said wheels to the outer end of the frame pivoted to the supporting-frame.

5. The combination with a traction device,

of a spring carried thereby, a supportingframe pivotally connected with the traction device and adapted to have its inner end bearing against said spring, means carried by the traction device and engaging with the sup: porting-frame for adjusting it, a frame pivoted to the outer end of said supporting-frame, means carried by the traction device and engaging with said last-mentioned frame for adjusting it, a pair of wheels, and springs connected with the wheels and to the frame pivoted upon the supporting-frame, said springs adapted to connect the wheels to the frame pivoted upon the supporting-frame.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ANDRE CASTELIN.
